PHP - Showing A Thumbnail On Hovering Over A Link
Hi,
I've recently started working on a site that someone else created. I'm not advanced with PHP like the previous guy was, so picking it up as I go. Currently there is an admin page for managing a database of images uploaded by users. The table on this page grabs the database field values and just fills in the table with tick boxes, etc to manage. Rather than display thumbnails of each of the images on the page directly, the website owner wants to have a list of links to images in the table (this is done), but on hovering over the link, show the thumbnail, have a pop up thumbnail right on the mouse cursor. There already exists the function to grab the thumbnail into the table, but I am unsure how to have this work in a hovering thumb image. Any help would be great. Similar TutorialsGoal: To have a gallery that downloads images from the folder I previously uploaded to in a previous script. Bug: When I load the page the thumbnail comes up as broken and when I click on the thumbnail to get the bigger picture it comes up with the following error message: "Firefox doesn't know how to open this address, because the protocol (c) isn't associated with any program." <?php include 'db.inc.php'; //connect to MySQL $db = mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASSWORD) or die ('Unable to connect.

I am getting no error message, but the connect string down to the end of the body section is showing up as plain text in my browser window. I do not know how to correct this. I have tried using two different types of connect strings and have verified my names from the HTML page are the same as listed within the php page. Suggestions on what I need to look for to correct would be great. I have looked online, but so far all I am getting is how to connect, or how to create a comment, so I thought I would try here.

Hi, I have this image gallery slideshow, below the image, it's the thumbnail pics. but the size of the thumbnail pics is random...I want to set the size to be the same for all thumbnail pics, since I'm not the one wrote the code so I'm just guessing that this is the php code for the gallery: Code: [Select] <?php for($i=1;$i<10;$i++) { if(!empty($foto[$i])) { if($i==1) { $foto_first=$foto[$i]; } echo "<img border=0 width=0px height=2px src='conf/i/".$foto[$i]."'>"; $dataku.="'".$foto[$i]."': { thumbnail: 'thumb/".$foto[$i]."'},"; } else { $i--; break; } } $dataku=substr($dataku,0,-1); ?> <link rel="stylesheet" href="css/slideshow.css"> <script src="js/mootools-1.3.1-core.js"></script> <script src="js/mootools-1.3.1.1-more.js"></script> <script src="js/slideshow.js"></script> <script src="js/slideshow.flash.js"></script> <script> window.addEvent('domready', function(){ var data = { <?php echo $dataku;?>}; new Slideshow.Flash('flash', data, { color: ['tomato'],duration: 1500, delay: 10000, height: 400, hu: 'conf/i/', width: 500}); }); </script> <div style="padding-bottom:350px;padding-right:100px"> <div id="flash" class="slideshow"> <img src="conf/i/<?php echo $foto_first; ?>" alt="1" height=100px><br> </div> </div> is this the part that I need to add "size" to it? $dataku.="'".$foto[$i]."': { thumbnail: 'thumb/".$foto[$i]."'},"; I'm totally newb at php, so I have no clue at all Hi all, completely new at this and have got myself stuck! I am trying to display a thumbnail image by connecting to my database and retrieving the URL that points to the image. I know that the connection is working but I can't seem to get it to point to the image. Probably something really simple. Here's my code: Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Image Swap Using CSS</title> <style type="text/css"> body { margin: 0; padding: 0; background-color:#000000; } img { margin: 0; padding: 0; border: none; } .test { margin: 0; padding: 0; width: 99px; height: 130px; } .test a:hover img { visibility:hidden; } </style> </head> <body> <?php // connect to the database mysql_connect("********", "****") or die(mysql_error()); mysql_select_db("eliteescorting") or die(mysql_error()); $start=0; // expand on the searches $data=mysql_query("SELECT * FROM escorts WHERE base = 'manchester' ORDER BY RAND()"); $num_results=@mysql_num_rows($data); for($ii = $start;$ii < $num_results; $ii++){ ?> <div class="test"><a href="#"><img src="<?php echo $data[$ii]['thumb'];?>" /></a></div> <?php } ?> </body> </html> In my mySQL field 'thumb' contains the full URL of the image ie http://www............ This is just for testing, I'll get round to sorting out security issues later. Your help will be greatly appreciated! Regards, Nortski. I want to resize both width and height of the thumb pic this is the php code <?php $id_member=$_SESSION['rid']; if(!empty($foto1_name)) { $nama_file=$foto1_name; $anton->sekur_upload($nama_file); if($valid) { $abpath = "conf/i/"; @copy($foto1, $abpath."/".$foto1_name); $abang_dom=$abpath."/".$foto1_name; list($width, $height) = getimagesize($abang_dom); if($width>200) { make_thumb("$abpath/$foto1_name","conf/i/thumb/$foto1_name",200); } else { $tujuan="conf/i/thumb/".$foto1_name; rename($abang_dom, $tujuan); } } $foto_old_name=$foto1_name; $foto1_name=$id_member."_".$foto1_name; $foto1_name=strtolower($foto1_name); $foto1_name=str_replace(' ', '', $foto1_name); $asal1="conf/i/".$foto_old_name; $asal2="conf/i/thumb/".$foto_old_name; $tujuan1="conf/i/".$foto1_name; $tujuan2="conf/i/thumb/".$foto1_name; rename($asal1, $tujuan1); rename($asal2, $tujuan2); } I want to set the size to 100 x 100, which part of the code that I need to edit? hi guys, im trying to resize and save a thumbnail version of images uploaded to my site in a sub folder (thumbs). I've currently got: $image=imagecreatefromjpeg($filepath); list($width, $height) = getimagesize($filepath); $new_width = 200; $new_height= 150; $image_p=imagecreatetruecolor($new_width, $new_height); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height); // Save the image imagejpeg($image_p, '/thumbs'.$filepath); // Free up memory imagedestroy($image_p); but it appears to do nothing, but it also doesn't return any errors? could someone help me out please? thanks! Is there any way to generate a small image of the 1st page of a pdf document without using a 3rd party like imagemagic. The site is hosted a register.com so I am thinking I am going to be limited to the basic php functions. I would be needing different picture sizes on different pages on my site but saving different sizes of a single pic is space consuming. I've heard that it's possible to automatically adjust the size of the picture and found a script that ought to make that possible. Unfortunately, it did not work for me.

Quote All it takes is replacing the "src" parameter in the <img> tag with the URL for the PHP script, including the parameters "src" which contains the path to the original image file, and "color" to select the color for the font. The script also supports a "width" parameter to specify the width of your thumbnail image. Using that script to display the above image as a thumbnail by setting the "src" attribute to "makeThumb.php?src=slides/slide1.jpg", we get the resulting image shown on the right. Can anyone please help me with this script or something similar? Thanks in advance. ^_^ Edit: The problem is that the image is not showing. It appears as if it cannot locate the file source. Hi! I'm looking for a script that can do the following: upload one or preferably fx. five image files(jpg) resizes them to a specific size if they exceeds that size. create a thumbnail No files above 100kb can be uploaded. uploaded and/or processed files must be renamed with a unique file name. Work with php5 I have searched the internet for a script like that, but I can't find one that matches my needs. Also, the code must include good comments and nott be to hard to understand. So as basic code as possible. Hi i am using a script to upload an image and resize it twice first to create the large image and then again to create a thumbnail. The large image is being created fine and is uploading ok.

I am really stuck any help would be much appreciated Hi all Let me start by saying I'm a noob - who is trying to sort (order) the displayed thumbnails from the script below. I've read the sort, explode, scandir and array manuals - but every attempt fails. I've been reading for days.. and still nothing. I got the script from the net.. While researching how to make this work, I found someone else using the same script needing help on your forums... (http://www.phpfreaks.com/forums/index.php/topic,299137.0.html) I've changed mine a little to work with the directories, and added Javascript for displaying the clicked thumb, in place. The entire thing works like a charm, and displays the generated thumbs and so on - its just that when it comes out on the page, it's in a random order like 2.jpg, 3.jpg, 1.jpg. (It always seems to display the first photo last.) I'd like it to display 1.jpg, 2.jpg, 3.jpg so they appear in order on the page. This way I can group black and white photos from color photos in the same category, or show photos in the order they happened on a vacation for instance. Thanks in advance for any insight! <?php $columns = 5; $thmb_width = 120; $thmb_height = 80; function resizeImage($originalImage,$toWidth,$toHeight){ list($width, $height) = getimagesize($originalImage); $xscale=$width/$toWidth; $yscale=$height/$toHeight; if ($yscale>$xscale){ $new_width = round($width * (1/$yscale)); $new_height = round($height * (1/$yscale)); } else { $new_width = round($width * (1/$xscale)); $new_height = round($height * (1/$xscale)); } $imageResized = imagecreatetruecolor($new_width, $new_height); $imageTmp = imagecreatefromjpeg ($originalImage); imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height); return $imageResized; } function generateThumbnails(){ global $thmb_width,$thmb_height; if ($handle = opendir("/full/path/to/images/galleryname/")) { while ($file = readdir($handle)) { if (is_file($file)){ if (strpos($file,'_th.jpg')){ $isThumb = true; } else { $isThumb = false; } if (!$isThumb) { $dirName = substr($file,0,strpos($file,basename($file))); if (strlen($dirName) < 1) $dirName = '.'; $fileName = basename($file); $fileMain = substr($fileName,0,strrpos($fileName,'.')); $extName = substr($fileName,strrpos($fileName,'.'), strlen($fileName)-strrpos($fileName,'.')); if (($extName == '.jpg') || ($extName == '.jpeg')){ $thmbFile = $dirName.'/'.$fileMain.'_th.jpg'; if (!file_exists($thmbFile)){ imagejpeg(resizeImage($file,$thmb_width,$thmb_height) ,$thmbFile,80); }}}}}}} function getNormalImage($file){ $base = substr($file,0,strrpos($file,'_th.jpg')); if (file_exists($base.'.jpg')) return $base.'.jpg'; elseif (file_exists($base.'.jpeg')) return $base.'.jpeg'; else return ""; } function displayPhotos(){ global $columns; generateThumbnails(); $act = 0; $img_dir = 'images/galleryname/'; if ($handle = opendir($img_dir)) { while ($file = readdir($handle)) { if (strpos($file,'_th.jpg')){ ++$act; if ($act > $columns) { echo '<li><a onclick="return showPic(this)" href="'.getNormalImage($img_dir.$file).'"><img src="'.$img_dir.$file.'" alt="'.$file.'"/></a></li>'; }}}}} ?> <script type="text/javascript" language="javascript"> function showPic (whichpic) { if (document.getElementById) { document.getElementById('placeholder') .src = whichpic.href; if (whichpic.title) { document.getElementById('desc') .childNodes[0].nodeValue = whichpic.title; } else { document.getElementById('desc') .childNodes[0].nodeValue = whichpic.childNodes[0].nodeValue; } return false; } else { return true; } }</script> <div class="galthumbs"><ul> <?php displayPhotos(); ?> </ul></div> <div class="galmain"><img id="placeholder" src="images/galleryname/1.jpg" alt="" /></div><p id="desc"> </p> Hi! my code uploads an image and saves it to an upload folder, but I want to create a thumbnail of it.
